The testicle ring is made from solid 925 sterling silver. The onyx ball is used to fasten the ring. This decorative item is used to manipulate the testicles. When the ring is put on, it prevents the testicles from coming into contact with the body, ensuring that they retain their good shape. It is available with an internal diameter ranging from 34 to 38 mm. As the testicle ring is made by hand, individual special requests can be processed using the internal diameter provided by you.
